Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Point localization super-resolution imaging (SR) requires dyes that can cycle between fluorescent and dark states, in order for their molecular positions to be localized and create a reconstructed image. Dyes should also densely decorate biological feature ...
Cellular homeostasis is maintained by tightly regulated gene networks, controlled notably at the levels of transcription, mRNA processing, and protein post-translational modification and turnover. This thesis focuses on two of these regulatory steps, namel ...
An emerging model views gene regulation as a competition for regulatory sequences between transcription factors and nucleosomes at thermodynamic equilibrium. A computational model of the DNA affinity of nucleosomes was recently developed allowing to predic ...
Living organisms consist of cells, the elementary components of which are proteins providing cellular structures and functionality. Nowadays, proteins of the size of one to a few tens of nanometers can be efficiently monitored by fluorescence microscopy an ...
DNA sequence variation has been associated with quantitative changes in molecular phenotypes such as gene expression, but its impact on chromatin states is poorly characterized. To understand the interplay between chromatin and genetic control of gene regu ...

Superresolution imaging is a rapidly emerging new field of microscopy that dramatically improves the spatial resolution of light microscopy by over an order of magnitude (similar to 10-20-nm resolution), allowing biological processes to be described at the ...
We review new and established methods for the chemical modification of proteins in living cells and highlight recent applications. The review focuses on tag-mediated protein labeling methods, such as the tetracysteine tag and SNAP-tag, and new developments ...
The ideal fluorescent probe for bioimaging is bright, absorbs at long wavelengths and can be implemented flexibly in living cells and in vivo. However, the design of synthetic fluorophores that combine all of these properties has proved to be extremely dif ...
Adrenergic receptors are a key component of nanoscale multiprotein complexes that are responsible for controlling the beat rate in a mammalian heart. We demonstrate the ability of near-field scanning optical microscopy (NSOM) to visualize b2-adrenergic rec ...
Background: Fluorescence loss in photobleaching (FLIP) is a widely used imaging technique, which provides information about protein dynamics in various cellular regions. In FLIP, a small cellular region is repeatedly illuminated by an intense laser pulse, ...
